Summer solstice: the longest and shortest day in 2016

The different ways people mark the longest, or shortest, day of the year and the first day of summer in 2016.

Monday’s solstice marked the point at which the Sun was at its northernmost point above the Earth.

The exact time this happens varies each year, but in 2016 it took place on June 20 at 22:34 GMT.

This made Monday the longest day of the year in the northern hemisphere, and the shortest day of the year in the southern hemisphere.

This year the solstice coincided with a full moon, which happens only every 70 years.
